Additive Manufacturing (AM) processes (1) Fused deposition modeling (FDM) (2) Stereo lithography (SLA) (3) Selective laser sintering /melting (SLM) (4) Laminated object Manufacturing (LOM) (5) Inkjet printing facilitate the manufacturing of arbitrary Three dimensional – configuration with exceptional degrees of freedom. Research and development is promptly advancing in this vicinity. Several divisions/sectors are now taking benefit from additive manufacturing to fabricate complex structures and attain the desired purpose for instance enhanced property of material, strength-to-weight ratio, increased utilized products, among others. Additive manufacturing (AM) satisfying demands with low cost and production time. In addition, defects are formed by sudden heating and cooling within additive manufactured components. A several studies have been developed treatments to recover it. Additive manufactured products by metal and their alloy, polymers and ceramics have under study to recognize their functions. In this comprehensive review paper highlights some key topics such as common methods; materials used applications and challenges which are crucial and more attentive. It is a comprehensive review for the purpose of maintaining the inter-relation between the assorted features. It is also demonstrated reliability of attained industrial products and applications.
